What is the solution 6x-19= 2(x-1) +11

stiv31 [10]

So because of PEMDAS you want to distribute the 2 to the parentheses so you'll get

6x-19=2x-2+11

Then you can just add like terms

6x-19=2x+9

Now you want to get all your variables on one side so you'd add 19 and subtract 2x

4x=28

Now you divide 28 by 4

x = 7

Zepler [3.9K]

Answer:

4x - 16

Step-by-step explanation:

A triangle is a three sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees

the perimeter of a triangle = sum of the side lengths

let the unknown length be represented with y

13x - 21 = 4x + 3 + 5x - 8 + y

13x- 21 = 9x - 5 + y

Make y the subject of the formula

13x - 21 - 9x + 5 = y

4x - 16 = y

the side length = 4x - 16
